  snap-site/styles.css — the one stylesheet every page of snap.bgsage.ai
  links (/styles.css, absolute, so the /<lang>/ copies the i18n build writes
  resolve it too). The visual system is docs/SNAP.md §2.2: the app's tokens,
  light-first with the dark counterparts under prefers-color-scheme, the
  app's type scale, a 4-pt spacing base and its radii. The site loads NO
  external font or script — the privacy page says it makes no third-party
  requests, so the type is the system stack. Gold and navy are Sage Pro's
  and never appear here; the only brand colour is the logo's maroon.
